Abstract
A cartridge tray seal for a chemical process tower. The seal includes a teflon impregnated fiberglass member which presents a generally flaccid sealing element. The member is folded within a generally u-shaped channel positioned around the perimeter of the cartridge tray. A securing strap is positioned within the u-shaped channel to sandwich the fiberglass material therein in a configuration for presenting a pair of outwardly extending sealing lips for engagement against the shell wall. This double pliable seal is able to accommodate shell wall deformations and out-of-round conditions which would ordinarily result in liquid and/or vapor leakage around the cartridge tray.
Claims16
An improved cartridge tray seal for a chemical process tower of the type wherein a cartridge tray is disposed within a tower shell for the passage of vapor and liquid thereacross and therethrough, wherein the improvement comprises said cartridge tray housing a peripheral sealing section adapted for abutting engagement with said shell, said sealing region including a generally flaccid member impregnated with material for resisting the liquid and vapor within said process tower and means for securing said flacoid member about said sealing region for permitting said sealing member to extend outwardly therefrom into engagement with said shell wall.
The apparatus as set forth in claim wherein said generally flaccid member is secured about said sealing region in a configuration forming a double pliable seal.
The method of sealing a cartridge tray within the shell of a chemical process tower comprising steps of:
- providing a flaccid member for positioning within the sealing region of said cartridge tray;
- impregnating said flaccid member with a material for resisting the chemical effects of the liquid and vapor of said chemical process tower;
- securing said flaccid material within said sealing region of said cartridge tray;
- and
- extending said flaccid material outwardly from said sealing region into engagement with said side walls of said shell for the sealed engagement of said tray thereagainst.
An improved cartridge tray seal for a chemical process tower of the type wherein a cartridge tray is disposed within a tower shell for the passage of vapor and liquid thereacross and therethrough, wherein the improvement comprises;
- said cartridge tray housing a peripheral sealing section comprising a generally U-shaped channel adapted for abutting engagement with said shell;
- said sealing region including a generally flaooid member impregnated with material for resisting the liquid and vapor within said process tower;
- fastener means for positioning upon said flaccid material and within said channel for the secured engagement thereof for securing said flaccid member about said sealing region and permitting said sealing member to extend outwardly therefrom into engagement with said shell wall;
- said flaccid material comprising teflon impregnated fiberglass;
- and
- said fiberglass being provided in a width sufficient to permit its folded placement within said sealing region with two sides thereof extending outwardly therefrom for forming a double lip seal against said shell wall.
The method of sealing a cartridge tray within the shell of a chemical process tower comprising steps of:
- providing a flacoid member for positioning within the sealing region of said cartridge tray;
- impregnating said flaccid member with a material for resisting the chemical effects of the liquid and vapor of said chemical process tower;
- cutting said flaccid material in a width sufficient for extending outwardly from said sealing region when secured therein;
- folding said flaccid material relative to said sealing region for extending two surfaces thereof outwardly into engagement with said shell wall;
- securing said flaccid material within said sealing region of said cartridge tray;
- and
- extending said two surfaces of said flaccid material outwardly from said sealing region into engagement with said side walls of said shell for the sealed engagement of said tray thereagainst.
